Improvement in fire-places



MARK ANTHONY OUSHING, OF AURORA, ILLINOIS.

IMPROVEMENT IN FIRE-PLACES.

Specification forming part of Letters Patent No. 117,053, dated July 18,1871.

To all whom it may concern:

Be it known that 1, MARK ANTHONY OUsH- ING, of Aurora, Kane county andState of Illinois, have invented a new and useful Improvement in Stovesand Open Grates for warming purposes; and I hereby declare the followingto be a full and accurate description of the same, reference being hadto the accompanying drawing and to the letters of reference markedthereon, and forming a part of this specification, the same lettersrepresenting the same part of the improvement.

My improvement has for its object the application of the principles ofmy hot-air furnace as applied and patented by me on the 6th day of July,1869, to open stoves and fire-place grates, so arranged as to combine myradiator with an open stove or grate suited to the use of bituminous andother soft coal, consuming the smoke and gases arising during thecombustion of the same.

In the accompanying drawing, Figure 1 is a front view of a grate andmantel-piece, in which is included my said improvement; and Fig. 2 is asectional view of the same, showing the several parts of theimprovement. Fig. 2 is a representation of the relative position of theseveral elements in combination, constituting my said improvement. Insaid figure g represents the position of the front part of the grate; f,the fireplace or position of the fuel to be consumed; a, the position ofthe diaphragm over the incandescent coal, to reflect the heat upon thesurface of the coal, thereby intensifying the same at that point, with aview of producing a more perfect combustion of the smoke and gasesarising therefrom. This diaphragm also checks the otherwise rapid escapeof the gases and smoke from the surface of the burning fuel, retainingthem longer in contact with the burning fuel, and thus favoring theirconsumption by the increased heat. Fig. 2 also represents the positionof my radiator R R, connected with the combustionchamber above thediaphragm by means of the pipe within which radiator is represented myadjustable escape-pipe p. The escapepipe is so arranged as to slide upand down upon the pipe 0 so as to vary the point of escape O atpleasure. By depressing the escape-pipe p until the part 0 is the bottomof the radiator, the smoke, gases, and other products of combustion canonly escape through the opening at the side and near the bottom of saidpipe. By elevating the pipe 19, which is done by means of force appliedto the cord, wire, or chain 8 acting over the pulley e, the point ofescape for the products of combustion entering the generator is broughtnearer to the pointof ingress, tending to produce a direct draught. InFig. 1 the front view of the grate, mantel-piece, and chimney-breastshows the position of the dampers d d for admitting cold air to thechamber surrounding the radiator 42 n n, and also the position ofthecord, Wire, or chain for raising up or depressing the movablefluepipe p and d d for letting out the heated air. Fig. 3 is a viewpresented by a vertical section taken longitudinally, showing a portionof the chamber of the radiator and the adjustable fliiepipe 1), theopening therein at 0, the registers leading into the chamber surroundingthe radiator d d and d d, and the registers leading into the chamberwithin the radiator at d.

The features peculiar to this improvement are the open grate orfire-place with the fixed diaphragm a, in combination with my radiator RR, containing the adjustable escape or exitflue pipe p, and may bebriefly described as a device for extending my improvements in hot-airfurnaces, patented in 1869, to fire-places and open-grated stoves.

Having thus fully described my said improvement in open stoves andfire-place grates, I will proceed to set forth the nature and extent ofmy claim.

I claim--- 1. The combination of my radiator and adjustable exit-fluepipe with an open-grated stove or fire-place, in the mannersubstantially as described, and with or without the fixed diaphragm a.

2. The iiXed diaphragm a, in combination with the fire-place andradiator R and the adjustable exit-flue pipe 19, substantially asdescribed.
